Hubble resolves myriad stars in dense star cluster (Omega Centauri Zoom)

Scientists have concluded the checkout period for NASA’s Hubble Space Telescope and are now revealing images showcasing the power of the much-improved observatory. This zoom into the globular star cluster Omega Centauri converges onto the Hubble Wide Field Camera 3’s panoramic view of 100 000 stars lying in the centre of the cluster. The stars vary in age and change colour as they get older. Most of them are middle-aged, yellowish stars like our Sun. But as they near the end of their lives, they balloon into red giants, and later still, into hot, blue stars.
